RGB LED Strip Circuit With Arduino: 4 Steps
But it still isn't throwing the solenoid even though it's lighting the LED and has a good 5 Volts. I've switched the relay board back to the 5v device and it works like a champ there. Where do you buy the PCB boards? I looked all over the page but couldn't find it. If I use an arduino board to send the signal to the transistor thru R2
Logic Level Converter Module for Arduino - Jaycar Electronics
Many of the most interesting sensors and devices are only available in 3. 3V or even lower voltage versions, which can be a problem if you want to connect them to a 5V microcontroller such as an Arduino.
Arduino’s AnalogWrite – Converting PWM to a Voltage
Arduino’s AnalogWrite – Converting PWM to a Voltage - When I first started working with the Arduino platform (it was also my first experience with microcontrollers), I was a little surprised that analogWrite

Regarding power, the Arduino requires 5V and the LED string needs 12v. If you want to use one power source, use a 12V power supply to power LEDs directly and use a voltage regulator (7805) before providing power to the Arduino. Step 3 of this instructable shows a diagram and explains this in greater detail. Hope this helps.

Blink. This example shows the simplest thing you can do with an Arduino or Genuino to see physical output: it blinks the on-board LED. Hardware Required. Arduino or Genuino Board optional LED 220 ohm resistor Circuit. This example uses the built-in LED that most Arduino and Genuino boards have. This LED is connected to a digital pin and its
